[0033] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present invention and should not be regarded as an improper limitation on the embodiments of the present invention.

[0034] In the description of the embodiments of the present invention, the "length direction" orientation or position relationship is based on the attached Figure 3 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the embodiments of the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the utility model.

[0035] The present invention provides an aerosol generating device for generating aerosol for a user to inhale. Figures 1 to 3 The aerosol generating device includes a housing 10 , an atomizer 20 and a battery 30 .

[0036] The housing 10 defines a mounting cavity 10 a therein.

[0037] An aerosol generating substrate is provided in the atomizer 20 for generating aerosol for inhalation by the user.

[0038] At least part of the atomizer 20 is disposed in the mounting cavity 10a. Thus, on the one hand, the housing 10 can provide a certain degree of protection for the atomizer 20, and on the other hand, the relative position of the two can be limited by the stopper cooperation between the inner wall of the mounting cavity 10a and the part of the atomizer 20 located in the mounting cavity 10a. The atomizer 20 is provided with an air inlet channel 20a and an atomizing cavity 25a.

[0039] The aerosol formed by the atomizer 20 is formed in the atomizing chamber 25a. The air outside the aerosol generating device enters the atomizing chamber 25a through the air inlet channel 20a. The airflow entrains the aerosol and then discharges the aerosol generating device for inhalation by the user.

[0040] The battery 30 is used to supply power to the atomizer 20 so that the atomizer 20 can convert the aerosol-generating substrate inside the atomizer 20 into aerosol.

[0041] It should be noted that the specific principle of supplying power to the atomizer 20 through the battery 30 to generate aerosol has been applied in the relevant technology and will not be elaborated here.

[0042] The battery 30 is disposed in the installation cavity 10a, so that the housing 10 can protect the battery 30 and reduce the probability of the battery 30 colliding with foreign objects outside the aerosol generating device during use, causing problems such as short circuits.

[0043] The battery 30 and the atomizer 20 are detachably connected, which means that the connection between the physical structures of the two can be released so that the two can be separated when necessary.

[0044] The battery 30 and the atomizer 20 are electrically connected, which means that the two can be electrically connected so that the battery 30 can supply power to the atomizer 20 .

[0045] It is understandable that, when the battery 30 and the atomizer 20 are separated, the electrical conduction between the battery 30 and the atomizer 20 may or may not be released.

[0046] The housing 10 includes a plurality of sub-shells 11 , and edges of at least some of the sub-shells 11 are detachably connected to each other to collectively enclose a mounting cavity 10 a .

[0047] In this way, an opening can be formed on the housing 10 by separating the edge of the detachably connected sub-shell 11 .

[0048] When the detachable sub-shell 11 is in the disassembled state, the installation cavity 10a is communicated with the outside of the aerosol generating device, so that the atomizer 20 and the battery 30 can be moved out of the installation cavity 10a from the communication position. In other words, the atomizer 20 and the battery 30 can be moved out of the installation cavity 10a from the opening formed by the edge of the disassembled sub-shell 11.

[0049] After the atomizer 20 and the battery 30 are removed from the installation cavity 10a, the atomizer 20 and the battery 30 can be disassembled and separated. That is, in this state, the aerosol generating device can be disassembled into at least three parts: the housing 10, the atomizer 20 and the battery 30. The edges of the sub-shells 11 are detachably connected, which is convenient for the operator to observe the detachable connection positions of each sub-shell 11 from outside the housing 10, and also convenient for the operator to apply force to the detachable connection positions of the sub-shells 11 from outside the housing 10 to achieve disassembly.

[0050] It is understandable that when the user inhales the aerosol, negative pressure is formed in the air inlet channel 20a and the atomization chamber 25a, so that the outside air enters the air inlet channel 20a through the entrance of the air inlet channel 20a under the action of air pressure.

[0051] It is understandable that, due to the air permeability of the material of the sub-shell itself and the seams between the detachable sub-shells, the outside air can pass through the shell and enter the installation cavity 10a.

[0052] The air inlet channel 20a and the atomizing chamber 25a are both sealed and isolated from the mounting chamber 10a, so that the gas cannot directly enter the air inlet channel 20a and the atomizing chamber 25a from the mounting chamber 10a.

[0053] The aerosol generating device in the embodiment of the utility model is provided with a detachable sub-shell 11, so that when the aerosol generating device has a use problem or the aerosol generating matrix is ​​exhausted, the atomizer 20 and the battery 30 can be taken out from the installation cavity 10a by disassembling the sub-shell 11, and then the atomizer 20 and the battery 30 can be disassembled according to actual needs to recover or replace the battery 30, and the atomizer 20 can be repaired, which is conducive to the recycling of various parts and related materials in the aerosol generating device; at the same time, it reduces the adverse effect of the gas directly entering the air inlet channel 20a from the installation cavity 10a into the air inlet channel 20a during the process of the user inhaling the aerosol, which is conducive to improving the user experience.

[0054] The detachable connection between the sub-shells 11 may be a connection mode that allows multiple disassembly and assembly, or a connection mode that allows only one disassembly after the installation is completed.

[0055] In some embodiments, see Figure 1The number of the sub-shells 11 is two, and the two sub-shells 11 cover each other to form the installation cavity 10a.

[0056] In some embodiments, the shell 10 is made of a degradable material. Thus, after the shell 10 is disassembled, even if it is directly discarded, it can reduce the adverse impact on the environment through natural degradation.

[0057] The specific type of material of the housing 10 is not limited, such as photodegradable plastic, biodegradable plastic, water-degradable plastic, paper, etc.

[0058] In some embodiments, the housing 10 is made of paper so that the user can separate the detachable connection position of the sub-shell 11 by directly tearing it, thereby facilitating the removal of the atomizer 20 and the battery 30 from the installation cavity 10a.

[0059] In the embodiment where the housing 10 is made of paper, there is no limitation on the manner in which the edge of the sub-shell 11 is detachably connected.

[0060] For example, the edges of the sub-shells are bonded to each other to reduce the manufacturing difficulty and improve the connection strength between the sub-shells.

[0061] The specific method for enabling the user to split the sub-shell 11 is not limited.

[0062] In some embodiments, see Figures 1 to 3 A seam 10b is formed at the connection position of two adjacent sub-shells 11, and a pulling piece 12 is provided on at least one side of the seam 10b perpendicular to its extension direction. The pulling piece 12 protrudes from the outer surface of the shell 10 and extends perpendicular to the extension direction of the seam 10b.

[0063] In this way, it is convenient for the user to apply a pulling force to the pulling piece 12 to separate the two sub-shells 11 connected to each other at the seam 10 b near the pulling piece 12 , thereby simplifying the operation difficulty for the user.

[0064] The pulling member 12 may be made of the same material as the housing 10 , or may be made of a different material.

[0065] In the embodiment where the material of the sub-shells 11 is paper, the contact surfaces of two adjacent sub-shells 11 forming the seam 10 b are bonded to fix the positions of the sub-shells 11 .

[0066] The width of the contact surface can be 1 mm to 10 mm. The specific width of the contact surface is not limited, for example, 1 mm, 2 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0067] In some embodiments, a mounting slot is provided on the atomizer 20 , and one side of the mounting slot is open so that the battery 30 can be inserted into the mounting slot through the open position of the mounting slot.

[0068] The mounting groove provides an installation position for the battery 30, so that the battery 30 can be taken out of the mounting cavity 10a together with the atomizer 20; at the same time, the position of the battery 30 constrained by the inner wall of the mounting groove reduces the probability of separation of the detachable connection between the battery 30 and the atomizer 20 or interruption of electrical conduction due to relative movement between the battery 30 and the atomizer 20, which is beneficial to improving the stability of power supply of the battery 30.

[0069] In some embodiments, the inner wall of the mounting groove perpendicular to the insertion direction of the battery 30 abuts against the outer surface of the battery 30 to achieve a detachable connection between the two through the friction force between the two.

[0070] The specific method of achieving electrical conduction between the atomizer 20 and the battery 30 is not limited.

[0071] For example, see Figures 3 to 8 The aerosol generating device includes a conductive wire 40, a conductive pin 50 and a conductive connector 60. One of the conductive pin 50 and the conductive connector 60 is electrically connected to one end of the conductive wire 40, one of the battery 30 and the atomizer 20 is electrically connected to the other end of the conductive wire 40, and the other of the conductive pin 50 and the conductive connector 60 is electrically connected to the other of the battery 30 and the atomizer 20. The conductive pin 50 can be inserted into the conductive connector 60 to electrically connect the two.

[0072] A conductive through hole is provided on the conductive connector 60, and a conductive elastic member is provided on the inner wall of the conductive through hole. The conductive elastic member can produce elastic deformation in a direction perpendicular to the extension direction of the conductive through hole. The conductive pin 50 is inserted from the conductive through hole and abuts against the conductive elastic member to compress the conductive elastic member, so that the conductive pin 50 is in a state of being fitted with the conductive elastic member and the inner wall of the conductive through hole respectively, thereby suppressing the conductive pin 50 from coming out of the conductive through hole through friction. By applying a force in a direction away from each other to the conductive pin 50 or the conductive connector 60, which is greater than the friction between the conductive pin 50 and the conductive connector 60, the conductive pin 50 is pulled out of the conductive through hole, so that the conductive pin 50 and the conductive connector 60 are separated. In this way, a detachable connection between the conductive connector 60 and the conductive pin 50 is achieved.

[0073] The conductive elastic member can be directly electrically connected to the battery 30 , or the conductive wire 40 can be electrically connected to the battery 30 and the conductive elastic member to achieve electrical connection between the two.

[0074] In this way, an indirect detachable connection and electrical conduction between the battery 30 and the atomizer 20 are achieved through the conductive pin 50 and the conductive connector 60. At the same time, since the conductive wire 40 is a flexible structure, it is convenient to flexibly arrange the relative positions of the battery 30 and the atomizer 20 by bending the conductive wire 40, which is beneficial to improving the space utilization in the installation cavity 10a and making the structure of the aerosol generating device more compact.

[0075] It should be noted that the specific structure of the conductive pin 50 and the conductive connector 60 and the specific method of achieving electrical conduction between the two have been applied in the relevant technology and will not be elaborated here.

[0076] The specific type of the conductive connector 60 is not limited, such as a four-hole wire connector.

[0077] In some embodiments, see Figure 4 and Figure 5 There are two conductive wires 40, which are respectively configured to correspond to the positive electrode and the negative electrode of the battery 30.

[0078] In some embodiments, there are two conductive pins 50 , which are respectively configured to correspond to the positive electrode and the negative electrode of the battery 30 .

[0079] The specific structure of the atomizer 20 is not limited.

[0080] For example, see Figures 3 to 8 The atomizer 20 includes a pneumatic switch 21, an atomizer core 22 and an atomizer seat 25. The atomizer seat 25 is provided with an atomizer chamber 25a, a pneumatic channel 25b and a first air inlet sub-channel 25c. The atomizer core 22 is located in the atomizer chamber 25a. The pneumatic channel 25b communicates with the installation chamber 10a and the first air inlet sub-channel 25c. The first air inlet sub-channel 25c communicates with the outside of the shell 10 and the atomizer chamber 25a. The pneumatic switch 21 is blocked in the pneumatic channel 25b. The first air inlet sub-channel 25c is at least a part of the air inlet channel 20a.

[0081] The aerosol generating substrate is stored in the atomizing core 22, and the atomizing core 22 is electrically connected to the battery 30. When the battery 30 supplies power to the atomizing core 22, the aerosol generating substrate in the atomizing core 22 forms an aerosol for the user to inhale.

[0082] The first air inlet sub-channel 25c is communicated with the atomizing chamber 25a so that the air pressures in the two are substantially the same.

[0083] One end of the pneumatic channel 25b is connected to the first air inlet sub-channel 25c, so that the sensing area of ​​the pneumatic switch 21 facing this end can sense the air pressure in the first air inlet sub-channel 25c; the other end of the pneumatic channel 25b is connected to the installation cavity 10a, so that the sensing area of ​​the pneumatic switch 21 facing this end can sense the air pressure in the installation cavity 10a.

[0084] When the user inhales the aerosol, an air pressure difference is generated between the first air inlet sub-channel 25c and the mounting cavity 10a. The pneumatic switch 21 can control the timing of the battery 30 supplying power to the atomizer core 22 to generate aerosol by sensing the air pressure difference.

[0085] It is understandable that only when the air pressure difference reaches a preset amplitude can the pneumatic switch 21 control the atomizer 20 to generate aerosol.

[0086] It is understandable that, during the process of the user inhaling the aerosol, the air outside the shell 10 can pass through the shell 10 into the installation cavity 10a, which is not conducive to the amplitude of the air pressure difference between the first air inlet sub-channel 25c and the installation cavity 10a reaching the requirement of triggering the pneumatic switch 21 to control the nebulizer 20 to produce aerosol.

[0087] In some embodiments with a pneumatic switch 21, an atomizer core 22 and an atomizer seat 25, see Figures 3 to 5 The atomizer 20 also includes an isolation cover 23 and an electrode column 24. The isolation cover 23 is sealedly covered on the atomizer seat 25 to enclose an isolation chamber 23a. One end of the electrode column 24 passes through the atomizer seat 25 and is electrically connected to the atomizer core 22, and the other end is located in the isolation chamber 23a. The first air inlet sub-channel 25c and the pneumatic channel 25b are both connected to the isolation chamber 23a and the atomizer chamber 25a. One end of the conductive pin 50 seals through the isolation cover 23 and extends into the isolation chamber 23a and is electrically connected to the electrode column 24. The isolation cover 23 is provided with an air flow channel 23b, which connects the isolation chamber 23a and the outside of the shell 10. The first air inlet sub-channel 25c, the air flow channel 23b and the isolation chamber 23a form an air inlet channel 20a. The conductive connector 60 is detachably connected to the isolation cover 23 and is electrically connected to the conductive wire 40.

[0088] Through the sealing cooperation between the isolation cover 23 and the atomizer seat 25, the isolation chamber 23a and the installation chamber 10a form a space that is independent of each other in terms of airtightness. The air in the installation chamber 10a and the air in the isolation chamber 23a do not flow, so it is difficult to affect the air pressure change in the isolation chamber 23a. Therefore, when the user is inhaling, even if the outside air passes through the housing 10 and enters the installation chamber 10a, it is difficult to affect the air pressure in the isolation chamber 23a.

[0089] At the same time, the conductive pin 50 is sealed and fixedly arranged with the isolation cover 23, so that it is difficult for the gas in the installation cavity 10a to enter the isolation cavity 23a through the seam 10b between the conductive pin 50 and the sealing cover.

[0090] The battery 30 is electrically connected to the atomizer core 22 through a conductive path formed by the conductive wire 40 , the conductive connector 60 , the conductive pin 50 and the electrode column 24 in sequence.

[0091] In this way, the pneumatic switch 21 senses the air pressure difference between the isolation chamber 23a and the atomization chamber 25a, thereby achieving the purpose of controlling the timing of the battery 30 supplying power to the atomization core 22; the adverse effect of the air permeability of the paper material on the air tightness in the installation chamber 10a, and the negative impact on the normal operation of the pneumatic switch 21, are reduced, thereby improving the user experience.

[0092] It can be understood that the conductive connector 60 is detachably connected to the outer surface of the isolation cover 23 to facilitate assembly and disassembly operations.

[0093] The specific method for achieving the detachable connection between the conductive connector 60 and the isolation cover 23 is not limited.

[0094] Exemplarily, one of the conductive connector 60 and the isolation cover 23 is provided with a slot, and the other is provided with an elastic buckle, and the elastic buckle is elastically deformed to allow it to be inserted into or removed from the slot, thereby achieving a detachable connection between the conductive connector 60 and the isolation cover 23.

[0095] The specific method for achieving sealing between the isolation cover 23 and the atomization seat 25 is not limited. For example, a sealing ring is provided in the joint 10 b between the isolation cover 23 and the atomization seat 25 .

[0096] It is understandable that after the user finishes inhaling the aerosol, the aerosol remaining in the atomization chamber 25a can condense to form condensate. If the condensate comes into contact with the paper shell 10, it may cause corrosion, softening and other problems in the shell 10, and at the same time affect the user's grip on the shell 10 and affect the user's use.

[0097] Therefore, by providing the isolation cover 23 , the condensate can flow into the isolation cavity 23 a and be stored, thereby reducing the probability of the condensate flowing out and contacting the paper shell 10 , thereby protecting the shell 10 .

[0098] In some embodiments, see Figure 3 and Figure 4 The shell 10 is provided with an air inlet hole 10c, which connects the outside of the shell 10 and the installation cavity 10a. The outer surface of the isolation cover 23 is provided with an air inlet protrusion 231, which extends into the air inlet hole 10c. The entrance of the air flow channel 23b is arranged on the end face of the air inlet protrusion 231 perpendicular to the extension direction of the air inlet hole 10c.

[0099] In this way, on the one hand, it is beneficial for the isolation chamber 23a to be directly connected with the outside of the shell 10, further reducing the adverse effect of the gas in the installation chamber 10a on the air pressure change in the isolation chamber 23a; on the other hand, it is beneficial for the condensate of the aerosol in the isolation chamber 23a to flow directly out of the shell 10, reducing the probability of the condensate in the isolation chamber 23a flowing into the installation chamber 10a and contacting with the shell 10 for a long time and having an adverse effect on the shell 10, which is beneficial to improving the service life of the aerosol generating device.

[0100] In some embodiments, see Figure 3 The air inlet protrusion 231 is located at one end of the isolation cover 23 along the length direction of the aerosol generating device.

[0101] The length direction of the aerosol generating device refers to the straight line direction where the largest dimension of the three-dimensional dimensions of the aerosol generating device is located.

[0102] This helps to reduce the probability of the user blocking the entrance of the airflow channel 23b when holding and using the aerosol generating device.

[0103] It can be understood that the arrangement position of the conductive pin 50 is conducive to its installation and removal with the conductive connector 60 .

[0104] For example, see Figures 3 to 5 The conductive pin 50 and the battery 30 are arranged on opposite sides of the isolation cover 23 .

[0105] This helps to reduce the interference between the battery 30 and the atomizer seat 25 during the installation or removal of the conductive connector 60, thereby improving the convenience of operation.

[0106] In some embodiments, see Figure 4 A first wire groove 23c is provided on the side of the isolation cover 23 away from the atomizer seat 25. The first wire groove 23c is open on the side away from the atomizer seat 25 and passes through along the relative direction of the conductive pin 50 and the battery 30. The conductive wire 40 is embedded in the first wire groove 23c.

[0107] The inner wall of the first wire groove 23c can constrain the position of the conductive wire 40, thereby reducing the probability of the conductive wire 40 rubbing against the inner wall of the installation cavity 10a and other devices in the installation cavity 10a due to the movement of the aerosol generating device, and reducing the risk of damage to the conductive wire 40 due to friction and subsequent poor conductivity; at the same time, placing the conductive wire 40 in the first wire groove 23c is conducive to improving the compactness and consistency of the installation of the conductive wire 40.

[0108] It is understood that the battery 30 supplies power to the pneumatic switch 21 to enable it to operate.

[0109] The specific method of realizing that the battery 30 supplies power to the pneumatic switch 21 is not limited.

[0110] For example, see Figure 5 The atomizer 20 includes a first transfer wire 26, which is disposed in the isolation chamber 23a and connects the pneumatic switch 21 and the conductive pin 50 to electrically connect the two.

[0111] In this way, the purpose of supplying power from the battery 30 to the pneumatic switch 21 is achieved through the first adapter wire 26; at the same time, the flexible bending property of the first adapter wire 26 is utilized to make the relative position arrangement of the pneumatic switch 21 and the conductive pin 50 more flexible, which helps to make the structure of the atomizer 20 more compact.

[0112] In some embodiments, the electrode column 24 and the conductive pin 50 extend in the same direction, and their projections at least partially overlap on a projection plane perpendicular to their extending directions. This helps to shorten the size of the atomizer 20 along the extending direction of the electrode column 24, making the structure of the atomizer 20 more compact.

[0113] In some embodiments, the extension direction of the electrode column 24 and the conductive pin 50 is the length direction of the aerosol generating device.

[0114] The specific method for achieving electrical connection between the electrode column 24 and the conductive pin 50 is not limited.

[0115] For example, see Figure 5 The atomizer 20 includes a second transfer wire 27, which is disposed in the isolation chamber 23a and connects the electrode column 24 and the conductive pin 50 to electrically connect the two.

[0116] In this way, the battery 30 supplies power to the atomizer core 22 through the second adapter wire 27; at the same time, the flexible bending property of the second adapter wire 27 is utilized to make the relative position arrangement of the electrode column 24 and the conductive pin 50 more flexible, which is conducive to making the structure of the atomizer 20 more compact.

[0117] In some embodiments, see Figure 5 A fixing seat 251 is provided on the inner wall of the isolation cavity 23a, and the fixing seat 251 is provided with a second wire groove. The second wire groove passes through the fixing groove and is open on one side perpendicular to its passing direction. At least one of the first switching wire 26 and the second switching wire 27 is embedded in the second wire groove through the opening of the second wire groove.

[0118] The inner wall of the second wire groove serves to position and restrain the first transfer wire 26 and the second transfer wire 27, thereby reducing the probability of the aerosol generating device rubbing against the inner wall of the isolation cavity 23a and other devices in the isolation cavity 23a due to the movement of the first transfer wire 26 and the second transfer wire 27, thereby reducing the probability of poor conductivity caused by damage due to friction.

[0119] It can be understood that a portion of the isolation cover 23 and a portion of the atomization seat 25 together form the inner wall of the isolation cavity 23a.

[0120] It can be understood that one end of the first switching wire 26 and one end of the second switching wire 27 are electrically connected to the conductive pin 50 by soldering.

[0121] In some embodiments, the material of the housing 10 is degradable plastic, so that the gas outside the housing 10 cannot directly pass through the housing 10 and enter the installation cavity 10 a.

[0122] In some embodiments, see Figures 6 to 8 The atomizer 20 includes a pneumatic switch 21, an atomizer core 22 and an atomizer seat 25. The atomizer seat 25 is provided with an atomizer chamber 25a, a pneumatic channel 25b and a second air inlet sub-channel 25d. The atomizer core 22 is located in the atomizer chamber 25a. The conductive pin 50 passes through the atomizer seat 25 and is electrically connected to the atomizer core 22. The second air inlet sub-channel 25d communicates with the atomizer chamber 25a and the outside of the housing 10. The pneumatic channel 25b communicates with the installation chamber 10a and the second air inlet sub-channel 25d. The second air inlet sub-channel 25d forms the air inlet channel 20a. The pneumatic switch 21 is blocked in the pneumatic channel 25b.

[0123] That is to say, the conductive pin 50 plays the role of the conductive column in the aforementioned embodiment, and the conductive pin 50 can directly supply power to the atomizer 20 .

[0124] This helps to simplify the structure of the atomizer 20 and reduce the number of parts.

[0125] In some embodiments, see Figure 7 and Figure 8 A portion of the atomizer seat 25 is bent and extended to surround and form an escape groove 25e, and at least a portion of the conductive connector 60 is located in the escape groove 25e.

[0126] In this way, it is beneficial to make the extension direction of the second air inlet sub-channel 25d avoid the conductive pin 50 to avoid interference between the two; on the other hand, the inner wall of the avoidance groove can restrain and limit the conductive connector 60, reducing the probability of the conductive connector 60 and the conductive pin 50 being separated due to vibration and other reasons.

[0127] Various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.
